Research on Endurance Performance and Aerodynamic Characteristics of Chained-Wing UAVs
摘要
Abstract
The chained-wing technology based on wingtip docking can significantly improve the aerodynamic performance and endurance of traditional UAV swarms.This paper focused on chained-wing UAVs,employed the vortex lattice method to calculate aerodynamic characteristics of various geometric configurations.A comprehensive investigation was conducted on configuration effects,and an endurance performance model was developed to study wingtip connection impacts.Research results revealed that wingtip connection could significantly reduce induced drag.In 8-unit configuration,the maximum lift-drag ratio increased to 56.3 with 47％reduction in average cruise power,while endurance time and range improved by 94％and 92％respectively.Considering practical mission requirements and system reliability,the optimal number of chain-wing units should not exceed 8.Considering practical mission requirements and system reliability,the number of chained-wing units should not exceed eight.Configuration changes had minimal effects on the aerodynamic performance of the system;for example,when a relative roll angle of 20° occurred in a two-unit chained-wing UAVs,the lift coefficient decreased by a maximum of 5％,while the drag coefficient decreased by 2％.Increasing the dihedral and sweep angles of the wings reduced the lift coefficient of the system,indicating that rectangular straight wings are more suitable for the wing design of chained-wing UAVs.This study provide theoretical foundation for the design optimization and performance evaluation of chained-wing UAVs.关键词
